BARTON A. BALLOU, OF PROVIDENCE, RHODE ISLAND.

PIN.

SPECIFICATION forming part of Letters Patent No, 392,302, dated November 6, 1888.

Application filed April 19, 1888. Serial No. 271.299. (No model.)

and useful Improvement in Pins; and I declare the following to be a specification thereof, reference being had to the accompanying drawings.

Like letters indicate like parts.

Figure 1 shows the blank from which my improved pin is made. Figs. 2, 3, and t illustrate the several stages in the process of said manufacture. Fig. 4 represents the completed pin. Fig. 5 is a modified form of my invention.

In each of said figures I give two views, which are respectively a plan and a side elevation.

My invention relates to the pin tongues or stems of brooches and otherpins for ornamental wear. It has hitherto been common in constructing such pin-tongues to use a cylindrical shaft or wire properly pointed at one end and having a tube or butt attached to the opposite end. This tube is usually soldered to the stem or to an intermediate plate. By this soldering the parts are annealed and softened and the elasticity or resilience of the pin tongue is impaired or destroyed. Pins constructed in this manner are soon bent out of shape and are apt to improperly or insufficiently engage with the pin-catch, because the temper of the stock has been drawn by the operation of soldering. Moreover, the insertion of a plate between the tube and the pintongue prevents the tongue from lying as close to the back lining of the breastpin as is desirable; hence in Wearing breastpins whose tongues are thus mounted it is a common fault that the front or ornamental portion falls forward by its weight, instead of remaining in snug contact with the garment, as desired. A pin-tongue is exposed to its greatest. strain in that portion which lies nearto the hinge or joint, and not having been heretofore made stronger in thisportion has been liable to be badly bent there.

It is the purpose of my invention to obviate these difficulties. My improved pin has its pointed shaft and butt made of one piece of stock integral throughout without soldering, and that portion of the shaftnear the butt-end is enlarged diametrically to give additional strength.

In Figs. 1, 2, 3, and 4 I illustrate my invention as applied to that variety of pin-tongues which have a long pointed stem to engage with the pin-catch, and a branch pin of shorter length attached to it near the hinge and extending in a parallel direction. This kind of pin-tongue is useful to prevent the tipping for- Wardof the upper part of the breastpin and "confines it snugly to the garment. I do not, however, claim this form as new, but only my construction of it.

I cut out of sheet metal by a die and cutter a blank, A, (shown in Fig. 1,) consisting of an elliptical head, a, a body or stem, 6, and an arm or projection, 0, extending at a right angle from the stem near the head. I next operate upon this blank with adie and plunger,which give a cylindrical form to the parts I) c,as seen at d and e, and form the head a into an ellipsoid, f. The ellipsoid f is then flattened in a direction at a right angle to the former plane surface of the head a and shaped by a die and plunger into a butt or hingejoint, g, which then is centrally bored, as shown at h. The cylindrical parts 01 e are swaged down and form the elongated and pointed pins m m, having thelargest diameter in that portion adjacent to the butt-end, as shown at 0. The pin a is then bent, as shown in Fig. 4, and is ready to be attached to abreastpinin the usual manner.

In Fig. 5 I show a single pin-tongue made in the same manner, except that the blank A has no arm 0, and consequently no pin it.

As the bore h of the butt g is located very nearly in the axial lineof thepin, it is evident that the pin can be mounted more closely to the back lining of the breastpin than is possible with the usual construction.

It will be seen that I entirely dispense with soldering, and by the operation of swaging the temper of the stock is improved, so that the pinhas great elasticity and is especially strong at and near the butt. It is therefore more durable and retains its shape and resilience.

Although it is not new to furnish a pintongue with a branch pin parallel thereto, such branch pins have hitherto been attached to the main pin by soldering, and thereby the stock has been annealed and the temper of the pin impaired or destroyed. By making my improved pin of asingle piece ol'stoek I dis- 2. The improved pin tongue herein dopense with soldering entirely and both pins scribed, having the pointed stein m, the enare highly tempered by the operation delarged cylindriealportiono, and theboredbutt scribed. or hinge joint, all made of one piece of stock, I5

desire to seeure by Letters Patentl 1. The improved pin tongue herein del scribed, having the pointed stein m, the enlarged cylindrical portion 0, the branch pin n,

and the bored butt or hinge joint, all made of one piece of stock substantially as specified.
